Thanks, too for your kind words.<br />James Gurneyhttp://www.blogger.com/profile/01870848001990898499noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-24350956094551779362014-01-30T11:36:07.719-05:002014-01-30T11:36:07.719-05:00Hi, James, I&#39;m coming here from your snow post...Hi, James, I&#39;m coming here from your snow post today. Did you know that George Eliot wrote about this very effect in Middlemarch? She was a wonderful observer. My English Lit. professor picked out the passage and read it to us aloud as one of her favorite passages in the novel. Here it is: <br /><br />An eminent philosopher among my friends, who can dignify even your ugly furniture by lifting it into the serene light of science, has shown me this pregnant little fact. Your pier-glass or extensive surface of polished steel made to be rubbed by a housemaid, will be minutely and multitudinously scratched in all directions; but place now against it a lighted candle as a centre of illumination, and lo! the scratches will seem to arrange themselves in a fine series of concentric circles round that little sun. It is demonstrable that the scratches are going everywhere impartially and it is only your candle which produces the flattering illusion of a concentric arrangement, its light falling with an exclusive optical selection. These things are a parable. The scratches are events, and the candle is the egoism of any person now absent...<br /><br />And then she goes on with her story. <br /><br />Thank you for your wonderful blog, I have been enjoying it very much the last couple of days. Your little explanation of light--that all would be formless darkness without a specific light source--was a total &quot;lightbulb&quot; moment for me. You are also very generous with taking the time to check out your readers&#39; work. Someday I&#39;ll post some. My favorites of yours are your plein air paintings of everyday places like the McDonalds&#39; sign.

At night the street lights will reflect off each of the smudged lines forming a long line of light similar to that found by looking at many puddles or waves on the water reflecting the same light source back to the eye. An effect that some lenses create, I assume, with concentric rings giving a star shape to a light source. Love all your posts James. I realize this is a little bit different than the phenomenon you were describing.Jon Hrubeschhttp://www.blogger.com/profile/01430340704506028602noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-7957337636049009842008-06-07T20:32:00.000-04:002008-06-07T20:32:00.000-04:00Cobwebs on the grass at dawn.
